Safety performance
Sulzer aims to maintain an Accident Frequency Rate (AFR) below 1, an Accident Severity Rate (ASR) below 15 and a Total Accident Rate (TAR) below 13. In 2025, the AFR was recorded at 0.7, below the defined target. The ASR was recorded at 20.4, exceeding the target. The TAR was recorded at 10.6, meeting the target and demonstrating the effectiveness of our safety initiatives.
Sulzer continues to enhance its accident prevention strategy by strengthening risk mitigation measures and reinforcing safety protocols. In November, Sulzer conducted Global Safety Week across all operations worldwide as a coordinated, company-wide initiative. Throughout the week, Sulzer teams all around the world participated in safety walks, workshops, trainings, and surveys, supporting open dialogue and shared learning. These activities reinforce safety and health as a core priority and collective responsibility across the organization.
For 2026, Sulzer will focus on advancing safety initiatives by incorporating new technologies, enhancing training programs, and maintaining employee engagement in safety activities. The aim is to further reduce incidents, continuously improve safety performance, and foster a safe working environment.
Flow
Flow’s accident frequency rate (AFR) decreased from 1.4 cases per million working hours in 2024 to 1.2 in 2025. This is above the target of 1.0 cases per million working hours, and concerted efforts will be undertaken in 2026 to decrease the division’s AFR through strengthened safety measures and communications. The division’s accident severity rate (ASR) decreased to 18.4 lost days per million working hours, down from 29.5 the previous year.
During 2025, Flow introduced the ESH X‑Audit, a cross‑site assessment program developed to align safety practices and reinforce core operational practices. The audit uses a standardized template covering 15 ESH areas to identify gaps and document required actions. These efforts support the harmonization and standardization of safety processes across sites.
Services
Sulzer Services’ accident frequency rate (AFR) was even lower in 2025 than in 2024 – with 0.3 cases per million working hours (2024: 0.4), a figure below the industry standard of 1.0. for the third year in a row. The accident severity rate (ASR) increased in 2025 to 24.8 lost days per million working hours (2024: 6.6).
During the year, Services supervisors and site managers participated in a training program developed in alignment with internationally recognized standards. By the end of 2025, 94% of supervisory and site management personnel had completed the training. The initiative supported consistency in risk‑assessment practices, more structured root‑cause analysis, and clearer ESH‑related discussions across teams.
Chemtech
Chemtech’s accident frequency rate (AFR) decreased from 1.5 cases per million working hours in 2024 to 0.7 in 2025. This figure below the target of 1.0 cases per million working hours shows the concerted efforts undertaken in 2025 to decrease the division’s AFR through strengthened safety measures and communications. The division’s accident severity rate (ASR) also decreased to 17.5 lost days per million working hours, from 21.3 in the previous year.
During 2025, Chemtech developed a Working at Height initiative on reducing fall‑related risks, updating and standardizing guidelines, trainings, and reinforcing competencies. The program emphasizes fall‑prevention measures such as equipment inspection, use of approved anchor points, secured tools, and access restricted to authorized personnel. These activities form part of Sulzer's ongoing efforts to maintain consistent safety practices across operations.
